Double mouse on Hi-Dpi screen

Zorin 16.1 install on Hi-Dpi screen with fractional scaling of 125%. On each boot, I'm greeted with two mouse pointers, one of which is dead (the right side one) and will stay there, the left one works properly. The only solution is to turn off the fractional scaling and turn it back on again.

Also why is the fractional scaling a user-specific setting and not a system wide thing ?? ( I ask because my boot-up login page is scaled to 100% and only after I login, the OS scales to 125%.

Same problem here on my Lenovo Yoga laptop with bluetooth mouse.
